This book illustrates key sustainability issues in global textile and fashion value chains, by examining individual types of fibers either at a single step in or along the entire value chain. It approaches sustainability-related issues in the textile and fashion value chain from an interdisciplinary and holistic viewpoint, with each contribution linking questions on the textile and fashion value chain to various drivers, indicators and concepts of sustainability. Each chapter represents a single step in the textile and fashion value chain, exploring and considering a wide range of interwoven and interdependent technological, environmental, social, political and economic aspects. Various fibers, textile engineering and chemical treatment steps, as well as innovative business concepts and regulatory frameworks across the entire textile and fashion value chain are identified, analyzed, discussed and critically evaluated.   The book provides a systematic overview of the potential and challenges of sustainable textile and fashion value chains, making it of interest to practitioners and scientists in sustainability science, environmental economics, and business, management and innovation. Further, it offers a valuable source of information for industrial and mechanical engineering researchers, and for students in the areas of textile engineering, fashion, or the apparel and clothing industry.
